Table 6 Recommended Safe Sizes When Mounting Detector on
the Safe Door Recommended Detector Locations
Detector on safe door:
If necessary, the detector can be mounted on the safe door (single
door only). Mount the detector 1.75" from the edge of the hinge side
of the door, centered on equal distance between both hinges.
Fig. 9 shows the recommended detector location when mounting the
detector on the door.
Note: When the detector is mounted on the safe door, the maximum
linear distance decreases to 73.5" from the sensor location, through
the hinges, to all points on the safe body.
EVD-1 Mounting on Safe Door
Typical UL Complete Safe Installations
1. Install in accordance with Underwriter Laboratories’ standard UL
681.
2. Install EVD-1 detectors in recommended locations at
recommended spacings.
3. Install UL listed, high security contacts on the exterior of the safe
or UL listed, ordinary use contacts on the inside of the safe.
4. Wire detectors and safe door contacts as shown in Figures 2 and
3a.
5. Listed power supply or control unit must provide at least 4 hours
of standby power for mercantile alarms and 72 hours of standby
power for bank vault alarms.
Typical UL Complete Vault Installations
1. Install in accordance with Underwriter Laboratories’ standard UL
681.
2. Install EVD-1 detectors on interior walls, ceilings, and fl oors,
spaced as shown in Figure 7. Refer to Table 6 for maximum
spacing on various materials.
3. A detector must be installed on the vault door if the net steel
thickness is less than 1 1/2 inches.
4. Wire detectors and door contacts as shown in Figures 2 and 3a.
5. Listed power supply or control unit must provide at least 4 hours
of standby power for mercantile alarms and 72 hours of standby
power for bank vault alarms.
EVD-1 Wall Protection
Figure 7 shows the rectangular areas of 100% coverage when
detectors are installed adjacent to one another. The detector spacing
is the sensor center point distance between adjacent detectors. The
detector spacing is the same as the width of the rectangular area of
100% coverage. Table 6 lists the dimensions of the rectangular areas
of 100% coverage on continuous surfaces for several materials and
sensitivity settings. When a surface extends around a corner via a
solid connection, detector coverage extends into that surface, but the
coverage is reduced to 3/4 of the remaining detector range. All joints,
cracks, and corners dampen structure borne vibrations. Vibration
transfer across these imperfections must be tested to ensure complete
coverage within the detector's range. Modular constructions require
one detector per panel and must be constructed of the materials listed
in Tables 3 and 6.
